Cheung Tin-chi (張天志) is a rickshaw driver and a former Chinese Wing Chun grandmaster.

He is the deuteragonist and final antagonist of the 2015 film Ip Man 3.

Ip Man 3
Cheung Tin-chi first appears after he arrives at Ip's house to pick up his son after his son got invited to their home for dinner. Although Cheung interacts cordially with Ip, he secretly envies and seeks to surpass him - participating successfully in underground fights to earn extra money.

That night, when Ip and his students fend off an attack by Ma's men, who attempt to set fire to the school and kidnap the headmaster. Cheung, who happened to be passing by, helps fight off the invaders and rescues the headmaster. Cheung's skills impress Ip, and he thanks Cheung for his help.

Local triad boss Ma King-sang later finds Cheung and offers him a large sum of money to get revenge against Tin on his behalf. Desperate to open his own martial arts school, Cheung accepts the offer and is able to put Tin in the hospital. Ip receives a call from the hospital and visits Tin.

Upon learning that his son was also kidnapped, Ip realizes it was a set-up by Ma to lure him away from the school, so that his gang could kidnap some of the students, including Ip Ching and Cheung Fung. Cheung arrives and is allowed to leave with his son due to being an associate; but after his son tells him that they still have his friends, he returns and fights alongside Ip. Ip and Cheung are able to hold their own until a troop of policemen led by Fat Po comes to arrest the gang, while Ma flees and is later attacked by his boss Frank for his faliure; Ip Man, after surviving an assassination attempt from Frank's asssasin called Muay Thai Warrior, later confronts Frank in a showdown between them that ends with Frank agreeing to leave him and the school alone.

Soon afterwards, Cheung uses the money he obtained from Ma earlier to opens his own martial arts school,. He soon claims that his Wing Chun is genuine while Ip's is not, and proceeds to build his reputation by defeating a number of martial arts masters. Eventually, he challenges Ip to a battle that will decide who is the true Grandmaster of Wing Chun. Meanwhile, Ip spends more time with his ailing wife, ashamedly feeling that he had neglected her earlier. Ip refuses to attend the match, instead going out dancing with Wing-sing, instructed by Lee, whom Ip finally accepts as a student. Due to Ip's failure to attend, Cheung is declared the winner, although he seems unsatisfied by Ip's refusal to fight him. Wing-sing, despite being happy about Ip's decision to accompany her, makes an appointment with Cheung for another match on Ip's behalf, as she guesses that Ip would have attended if not for her condition.

Wing-sing accompanies Ip to the fight. After a battle with six and a half point poles, butterfly swords and an empty-handed fight, Ip eventually overpowers Cheung with a one-inch punch. Accepting defeat, Cheung destroys the banner that proclaimed himself to be the Grandmaster. Ip tells him that spending time with their closest ones is more important than competing.
